There are a lot of movie theaters in Vegas and I tend to frequent a select three. Green Valley is one of them. I particularly like this theater because it is situated in the perfect place. You can get to the theater without actually going through the casino, which I love. It has an entrance directly off of The District, which means it affords you the ability to have a lot of dining options if you want to do a dinner/movie. The casino's food court is also directly above the theater, which affords you a cheap, quick meal if you don't want to do a sit-down meal.
The theater itself is kept clean. It is on the small side, but I kind of like that about the place. You can usually catch movies here that have been out for awhile and you'll be able to watch it in a less than half full theater.
I rarely go to the box office anymore to buy tickets since I buy them online, so my dealings with the staff are rare. However, whenever I've given my ticket over to the ticket taker here they have been congenial and happy.
I would recommend this theater over many others in the Valley.
